Solving Quadratic Equations using the Quadratic Formula You must get equation equal to zero before you determine a,b, and c. General equation of a quadratic: Quadratic Formula: Notice where the letters come from for the formula We use the quadratic formula when something can not be factored. However, it also works for factorable quadratic equations as well.

Before you can find a,b, and c, you must get equation = to 0. Type what is under the radical exactly as written on your calculator.
